Getting error about translation

Hi,

After I’ve installed the plugin and gone into settings, I get an whitescreen together with the following error:

Notice: The language ‘sv_SE’ has to be added before it can be used. in /customers/a/2/6/kondens.com/httpd.www/wp-content/plugins/post-status-notifier-lite/lib/IfwPsn/Vendor/Zend/Translate/Adapter.php on line 443 Notice: No translation for the language ‘sv’ available. in /customers/a/2/6/kondens.com/httpd.www/wp-content/plugins/post-status-notifier-lite/lib/IfwPsn/Vendor/Zend/Translate/Adapter.php on line 456

I suppose it has something to do with my language settings? I’m using a swedish interface.
